WM. BAKER, OF UTICA, NEW YORK.

HINGE.

Specification forming part of Letters Patent No.` 8,869, dated April 13,1852i; Reissued August 28,

To all lwhom it 'ma/y concern:

Be it known that I, WILLIAM BAKER, of the city of Utica, in the countyof Oneida and State of New York, have invented a new and usefulVVindow-Blind Hinge and Fastener; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, making a partof this specification, in which- Figure l represents both the upper andlower hinges, as constructed for brick, or stone houses, and as seenupon the outside, the blind being hung and closed. Fig. 2, is the lowerhinge as seen separate from the blind, and in the position exhibitedwhen the blind is thrown open` and fastened. Fig. 3 is the like exhibitof the upper hinge when the blind is open and fastened. Fig. l is theunder, or stationary part of the lower hinge before mentioned. Figs. 5and 6 exhibit the upper and lower hinges as constructed for wooden orframe buildings, the backs of the hinges being here seen in the positionoccupied by them when the blind is closed. Figs. 7 and S show the outerends of the last mentioned hinges, and the locking and fastening of eachas seen when the blind is thrown back against the wall of the house.

The same letters refer to like parts in all the drawings.

Fig. 9 is an inside fastening used to fasten the blinds when closed. Itconsists of three parts or pieces. The frame A, B, which is screwed fastto the insideof the blind frame C, D, the latch E, andthe catch K,

the latter being screwed down upon the window bench in a positionsuitable to receive the latch E, when the blind is brought vFig. l.

tion with a hook and catch attached and connected in the mannerhereinafter de scribed, the whole forming a fastening and the mode ofoperatingithe same; the fastening taking hold of and pulling directlyupon the window casing and the blind, and thus relieving the hinge.

The mechanical contrivance by which this principle, or plan of fasteningis applied, is simple `and without complication. It is operated by asimple, and convenient effort of the hand at the heel of the blind,exerted in the ordinary way of closing the blind, so that all liabilityto accident from mistake, in attempting to close the blinds withoutunderstanding the fastening is also avoided, and this is done withoutincreasing the usual number of parts or pieces composing an ordinarybutt. l

rllhe annexed drawings fully show the form and construction of thehinge. A single hinge consists of only two parts: the pin and the eyewith their appendages. The agency by which the blind is raised andlowered, `belongs tothe lower hinge. It consists in the bridge, orinclined plane a (Fig. 4) cast solid at the base of the pin P, inconnection with an elongated aperture in the eye, and the counter hooksz" and C (Figs. l, 2 and 8). The pin is round, as usual, taperingslightly to the top. The bridge a is an oval projection, as indicated inthe drawing, extending in the direction of the catch C, about threesixteenth parts `of an inch horizontally at the base, and

parts of the hinge,\as when the blind is thrown open and fastened. Thehook i, as

`the blind swings around strikes the inner face of the catch C, whichassists in keeping `the eye elevated on` the bridge until the hoek i,passes the catch C, when the weight of the blind settles the eye to thebase of the bridge carrying out the hook z', and fastening it to thecatch as here seen. This will be more clearly understood by looking atthe back of the lower hinge as shown in Here it is evident if themovable art A is swun around in o eninO the Y plished. This is done bytaking hold of the corner ofthe blind, and pulling it toward you, in theordinary way of closing a blind. The force thus exerted with a slighteffort to raise the blind brings the eye of the hinge to the top of thebridge, sliding up o-n its inclined plane.- This disengages thefastening in both the upper and lower hinges, and the blind is readilybrought to a close. The

Y force thus exerted by the hand pulls the blind edgewise, and in thedirection of the extension of the bridge. vWhereas the force of the windwhen the blind is fastened or any other force calculated to bring theblind directly around, would not disengage the fastening. The inclinedplane or bridge here described for operating the fastening, may surroundthe pin, that is the whole base of the pin may form an inclined planedescending toward the catch C; in which case the base of the eye is madeto conform to it. In the operation of unfastening, the blind as beforedescribed is drawn edgewise in the direction from the catch C, the eyeslides up on the inclined base of the pin disengaging both fastenings inthe manner before described. No bridge, or inclined plane at the base ofthe pin, or elongation of the eye, are necessary on the upper hinge. Theoperation of the lower hinge gives a vertical Inotion -to the blind, andthis is dierent to fas-V ten and unfasten a vertical catch in the upperhinge. The hook and catch however are attached to, and extend from thewings, or screw plates of the hinge in a similar manner to those of thelower hinge, forming a fastening on the same principle, and with thesaine advantages as to strength and security, as that of the lowerhinge. The wings, or plates W, are the parts of the hinge lby which itis screwed to the blind, and

window casing. These form a line transverse to the extension of thehinge. They are screwed directly on the outside of the blind and windowcasing, as shown in Fig. l, and are consequently parallel vto each otherwhen the blind is thrown back against the wall, the fastening being inthe space between them. The hook and catch are cast solid with thehinge. A, A in the ligure represent the blind frame, and B, B', t-hewindow casing. The drawings show the hinge o-f the full size, as made inordinary cases, the wood work being here broken o" between the upper andthe lower hinge to bring them near together. The screw plates areextended in the directionhere described for the purpose of att-aching tothem the hook and catch for fastening. These plates may be made of theusual form to be screwed to the edge of the blind and the inside of thecasing, and a strap or back brace may be substituted, extending alongthe outside, to which the fastenings may be attached in like manner asdescribed, but this complication is avoided by using the screwplates forboth purposes.

Figs. 5 and 6 show the form of the hinge as constructed for wood orframe buildings, Fig. 5 being the upper and Fig. 6 the lower hinge. Theplan o-f fastening and the operation are substantially the same as thosebefore' described. The bridge, or inclined plane at the base of the pin,and the elongation of the eye are the same. The extension of the hingeis shortened to suit the slight projection of the clapboards beyond thecasing of the window. fl is the hook on the movable part of the hinge,and C the catch on the stationary part. The operation is similar to thatbefore described.

Figs. 7 and 8 show the manner in which the two parts of the hinge inthis case, are locked together when the blind is thrown back, Fig. 2being the upper and Fig. 8 the lower fastening. The distance from a, tob, denotes the extension of the hinge, or the distance from the casingto the back side of the blind in wooden buildings, as that from a to(Figs. 2 and 3) denotes t-he extension of the hinge in the case of brickand stone buildings. This extension in either case is of course to bevaried to suit the projection of the wall of the house beyond the windowcasing; and the hinges are in all cases to be made rights and'lefts tosuit the two sides of the window. In cases where extra strength isrequired, or for very heavy blinds, the movable part of the hinge may becast with an extension of the plate substantially as indicated Iby thedotted line F (Fig. l) reaching out upon the cross bar of the blind, andthus strengthening the blind frame.

I do not claim as new simply constructing the window blind hinge withits screwplates so arranged as to be screwed to the back of the blindand the outside of the window casing, but

I claiml. The bridge or inclined plane at the base of the pin and thecorresponding elongation of the eye operating upon and in connectionwith the hook and catch attached and connected in the manner described,the whole forming a fastening, and the mode of operating the same,-thefastening taking hold of and pulling directly upon the Window easing andthe blind and thus relieving the hinge as described.

2. I claim-the use of the bridge or inclined plane at the base of thepin, and the elongation of the eye as described, for disengaging theblind fastening, independent of its connection With my fastening asabove described, and Whether the fastening is connected With the hingeor not, the Whole be- 10 ing constructed and arranged substantially inthe manner above set forth.
